BUYSSE, OF DETROIT, MICHIGAN, ASSIGNOR INDUSTRIAL HEATING EQUIPMENT COMPANY, OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN APPARATUS FOR HEAT TREATING ARTICLES Application filed December 21, 1927. Serial No. 241,546.

My invention relates to apparatus for heattreating articles and an object of my improverr ents is to provide a compact and simple apparatus that shall-permit of the articles being properly subjected to the heat and which is economical in use.

I secure this object in the device illustrated in the accompanying drawings, in which Figure 1 is a sectional view of an apparatus embodying my invention. Figure 2 is a section on the line II, II, Fig ure 1.

Figure 3 is a section on the line III, III, Figure 1.

Figure 4 is a detail sectional view, partly broken away, of a containing cylinder.

ab, ab, is a furnace consisting of the fire space a, a, and theheating space I). The heat produced in the combustion chamber a, a, passes up through fiues, not shown, into the heating chamber b.

0 is an enclosed ante-chamber to the 'heating chamber 6. d is the discharge flue through which the products of combustion pass out of the apparatus.

e,- e, are parallel downwardly inclined tracks leading from the front of the antechamber 0 at an entrance opening 0 passing through an opening ob into the heating chamber 6 and terminating toward the rear Wall of said heating chamber.

6 6 are two-parallel tracks extending from the rear of the heating chamber 6 in a downwardly inclined direction through an opening in the forward wall of said heating chamberinto the interior of the. antechamber a and passing out through the front wall of said ante-chamber at an opening 0. The tracks 6 6 are vertically below the tracks 6, e, and at their inward end curve upward, as shown at '6 Figure 1, to a point beyond and above thetracks e, e. I

9 indicates the cylindrical containers in which thearticles are placed and in which they may be packed in compound, if desired. g is a cover for the otherwise open end of a container 9 and this may be held in position by a through-rod 9 as shown in Figure 4, or otherwise. 4 A p The containers 9 are placed upon the tracks e, e, at the opening 0 and roll along said tracks because of the inclined position of said tracks. When a ,container has reached the inner ends of the tracks 6 it falls along the curved portion e of the tracks e and descends to the tracks rolling along the same, because of their inclined position, and passes from the heating chamber 6 to the antechamber 0 through the opening be and out of said ante-chamber at the opening 0.

The containers 9 are placed upon the tracks e and 6 so as to be contiguous to each other and form a continuous line along said tracks, as shown in Figure 1.

There is a continuous space, or passage, f extend ng at its ends by grooves f f 1n the side walls of the ante-chamber 0. This passage f extends through the wall between the' heating chamber 6 and ante-chamber 0 above the upper line of containers 9 and at its forward end communicates with the discharge flue d. The lower wall of the flue f is constituted of the continuous line of containers g.

h is an apparatus by which the discharge of the containers 9 from the opening 0 may be regulated so that a desired number of said containers shall be discharged during a certain time and thetime during which the containers are subject to the heating in the chamber b may be regulated.

'The method of using the above described apparatus is as follows:

The tracks 6, e being completely filled with containers 9, as shown in Figure 1, the heat produced in the fire space a, a, passes into the heating chamber In and heats the containers in said chamber. The hot gases passing itrom 6, assisting to raise the temperature of said 100 containers before they enter the heating chamber b.

-What I claim is:

1. In an apparatus of the kind described,

5 the combination of a heating chamber, an ante-chamber therefor, means for passing articles to be heated in a continuous line through said ante-chamber into said heating chamber and means for passing said articles in a continuous line from said heating chamber through said ante-chamber, said articles being adjacent to each other in the ante-chamber with an open space therebetween so that the heat of the articles passing from said heating chamber shall be imparted by direct radiation to the articles passing to said heating chamber in said ante-chamber, and a flue in said ante-chamber between the incoming articles and the adjacent wall of the ante- 0 chamber for the gases passing from said heating chamber of which flue the lower wall is formed by the articles passing through said ante-chamber to said heating chamber.

2. A furnace consisting of the combination of a heating chamber 6, an ante-chamber c therefor, an inclined track extending from the outer end of said ante-chamber through the same and into and to the rear wall of said heating chamber, an inclined track below the first mentioned track extending from the rear end of said heating chamber to and through said ante-chamber said furnace adapted to contain a continuous line of cylindrical articles upon said tracks, the

space between the lines'of articles on said tracks being open so that radiant heat may pass therethrough from the articles passing rom said furnace to the articles passing to said furnace.

40 3. A furnace consisting of the combination of a heating chamber 6, an ante-chamber c therefor, an inclined track extending from the outer end of said ante-chamber through the same and into and to the rear wall of said heating chamber, an inclined track below the first mentioned track extending from the rear end of said heating chamber to and through said ante-chamber said furnace adapted to contain a continuous line of cylindrical articles upon said tracks, said heating chamber opening to said ante-chamber above the articles on the first named track and communicating with the discharge flue above said articles on said first named track at a point remote from said heating chamber, said articles on the first named track constituting the wall of said flue, the space between the lines of articles on said tracks being open so that radiant heat may pass therethrough from the articles passing from said furnace to the articles passing to said furnace.

In testimony whereof, I sign this specification.

CHARLES E. BUYSSE.
